How a wall-mounted heat pump provides comfort — simply

A wall-mounted heat pump moves heat rather than creating it.

  • In summer : it captures the heat and humidity from the indoor air and releases them outside → air conditioning + dehumidification, more stable than a portable device.
  • In winter : it recovers the heat contained in the outside air (even in cold weather) and transfers it inside → high-efficiency heating, ideal for Montreal and its surrounding areas.

Inverter : Most of the models we install use a variable speed compressor. The machine automatically modulates its power to maintain the temperature smoothly , with less noise and less energy .

Smart defrost : In very cold weather, the outdoor unit may form frost. The system then switches to a short, automated defrost cycle to clear the heat exchanger, then resumes heating. This is normal and expected for our climate.

AirGreen Tip: A properly sized and well-placed heat pump dehumidifies better, heats longer at low speed (therefore silently), and consumes less. This is the basis for “no-think” comfort.

Interchange (serpentine)

This is the heat pump's "radiator." In cooling mode, the room's air passes over this cold coil: heat and humidity are captured, the air comes out dry and cool, and the water drips into the condensate tray. In heating mode, the coil becomes hot and transfers the heat to the air blown into the room. Made of copper/aluminum with fine fins to increase heat exchange, it is very sensitive to dust: clean filters and periodic cleaning maintain efficiency, reduce noise, and extend its lifespan. Do not bend the fins: they guide the airflow and make all the difference in efficiency.

Fan (Airflow / CFM)

The fan circulates air through the coil and into the room. Its flow rate (CFM) determines the blowing range: the higher it is, the further the air travels (useful in open areas or stairwells). Inverter models modulate the speed: at low speed, the air is softer, quieter , and dehumidification is better; at higher speed, the setpoint is quickly reached. Proper blade adjustment (indirect flow) prevents drafts on the couch or bed. Keep the filters clean : a clogged fan loses CFM, makes more noise, and consumes more. In short, the right CFM = uniform comfort, less noise, and efficiency.

Adjustable fins (direct/indirect flow)

The adjustable vanes guide the airflow blown by the wall head. They can be adjusted horizontally and vertically to direct the air where you want it. In direct flow mode, the air is sent directly towards the occupants for a quick cooling or heating effect. In indirect flow mode, it is distributed more gently and evenly throughout the room, ideal for prolonged comfort without unpleasant drafts.

On most modern models, these fins are motorized and programmable : you can adjust them remotely or let the automatic function manage the distribution according to the detected temperature. When properly oriented, they improve air circulation , dehumidification and the energy efficiency of your heat pump.

Temperature/Humidity Sensors

These sensors are the "eyes" of your wall-mounted heat pump. Discreetly integrated into the interior head, they continuously measure the room's ambient temperature and humidity level . Using this data, the unit automatically adjusts the compressor and fan speed to maintain a stable temperature and consistent comfort, without overheating or excessive cooling.

Recent models go further with intelligent dual-zone or infrared sensors, capable of detecting human presence and directing airflow toward—or away from—occupants according to your preferences. The result: a consistently perfect temperature, reduced energy consumption, and a feeling of “tailored” comfort, whatever the outdoor conditions.

Washable filter (and sometimes additional media)

The washable filter is the first line of defense for your wall-mounted heat pump. Located just behind the face of the indoor head, it captures dust, pet hair, and airborne particles before they can clog the coil. Easy to remove and clean with warm water, it should be serviced every 4 to 8 weeks during the operating season to maintain optimal airflow and healthy air quality.

Some high-end models also incorporate additional filter media —activated carbon filters for odors, antibacterial filters, HEPA filters, or ionizing filters—that further purify indoor air. A clean filter improves dehumidification , reduces energy consumption , and extends the life of the system . It's a small maintenance step, but a big impact on comfort and efficiency.

Wi-Fi / smart control options (depending on model)

Modern wall-mounted heat pumps can connect to your Wi-Fi network for smart, streamlined control . Using a mobile app or home automation platform (Google Home, Alexa, etc.), you can adjust the temperature, change modes, or schedule your home —no matter where you are.

Some apps even display energy consumption in real time , alert you when it's time to clean filters, or automatically adjust operation based on the outside weather. These smart features make comfort management more precise, more economical, and more environmentally friendly .

Bottom line: Wi-Fi turns your wall-mounted heat pump into a connected device that adapts to your lifestyle—and helps you keep your home comfortable without having to think about it.

Outdoor unit (compressor / condenser)

The “engine” of the system:

Inverter Compressor

The inverter compressor is the heart of the wall-mounted heat pump—it circulates refrigerant between the indoor and outdoor units. Unlike older fixed-speed (on/off) compressors, inverter technology continuously adjusts motor power based on actual heating or cooling needs.

Result: the machine never stops completely, it simply slows down when the temperature is reached, which helps maintain stable comfort , reduce power consumption and extend the life of the system .

This intelligent modulation also makes the unit quieter and more responsive —no more sudden temperature fluctuations or noisy startups. This is one of the key elements that sets a modern wall-mounted heat pump apart, especially in the Quebec climate where consistent performance in extreme cold is essential.

External exchanger

The outdoor heat exchanger —often called the condenser —is the component that allows the heat pump to transfer heat between the indoors and outdoors. It consists of a copper coil and aluminum fins, designed to maximize heat exchange with the ambient air.

In air conditioning mode , the exchanger releases the heat captured inside to the outside. In heating mode , it does the opposite: it captures the heat from the outside air (even in cold weather) and returns it to the house via the refrigerant.

To operate efficiently in the Quebec climate , the exchangers we install are designed with anti-corrosion coatings and optimized fin spacing to prevent snow and frost accumulation. Regular maintenance (gentle cleaning of the coil and clearing of the area) helps maintain optimal performance and ensure a prolonged life of the outdoor unit.

Outdoor fan

The outdoor fan circulates air through the compressor's heat exchanger. Its role is essential: it draws in outside air and passes it over the coil to promote heat exchange. In summer, it expels heat removed from the house; in winter, it helps the heat pump capture heat from the ambient air, even at very low temperatures.

Recent models use variable speed motors that automatically adjust airflow as needed, reducing noise , energy consumption and mechanical wear . The blade design is also optimized for smooth and quiet airflow , even in very cold weather.

A well-maintained fan—free from leaves, snow, and debris—ensures stable performance , efficient defrosting , and improved longevity of the outdoor unit.

Sporlan thermostatic expansion valve for HVAC systems, featuring copper fittings and metallic gray cap

Expansion valve (regulates the refrigerant)

The expansion valve is a key component of the refrigeration circuit: it controls the pressure and quantity of refrigerant circulating between the compressor and the evaporator. By reducing the pressure of the refrigerant, it causes it to cool instantly , allowing the indoor coil to efficiently absorb heat from the air (in air conditioning mode) or, conversely, to release it (in heating mode).

Modern wall-mounted heat pumps often use an electronic expansion valve (EEV) rather than a mechanical one. This system continuously adjusts the valve opening based on temperature, pressure, and actual comfort demand. The result: better thermal stability , higher energy efficiency , and longer compressor life thanks to more precise refrigerant control.

Reversible valve

The reversible valve is the element that allows the wall-mounted heat pump to operate in both heating and cooling mode . By simply changing the direction of the refrigerant flow in the circuit, this valve reverses the role of the two exchangers: the outdoor unit becomes a heat source in winter, and evacuates the heat in summer.

This switchover is fully automatic — controlled by the electronic card according to the mode selected on the remote control or Wi-Fi application. The switchover takes place in a few seconds, without manual intervention.

A well-designed reversible valve ensures a smooth transition between seasons , without loss of efficiency or mechanical jolts. This is what makes the heat pump a 2-in-1 system : a single device for efficient heating and cooling all year round.

Control card

The control board is the true command center of the outdoor unit. It orchestrates all the components—compressor, fan, reversible valve, sensors, and resistors—to ensure the heat pump operates accurately and efficiently.

It is this which automatically manages defrosting , monitors circuit temperatures and pressures , and adjusts the power of the Inverter compressor in real time according to the demand for heat or air conditioning.

On modern models, this electronic board features adaptive logic : it analyzes outdoor conditions, optimizes cycle times, and reduces energy consumption. It plays a vital role in system stability , component safety , and cold-weather performance —ensuring that your heat pump remains reliable and consistent, even in the depths of a Quebec winter.

Defrost tray heating base

The defrost pan heating base is a key element in ensuring the proper operation of the wall-mounted heat pump during Quebec's harsh winters. Located at the bottom of the outdoor unit, this electrical resistance prevents water from defrosting from freezing in the pan and blocking the fan or turbine .

Without this heating base, water could accumulate, turn to ice and impair drainage, causing noise, vibration or even complete system failure.

The resistance activates automatically during defrost cycles, only when the outside temperature requires it, which limits electricity consumption.

This simple but essential device helps extend the life of the outdoor unit , ensure free flow of melt water , and maintain consistent performance even under the worst winter conditions.

Behind the performance: the technical details that make all the difference

Because careful installation makes all the difference!

Refrigerant lines (copper)

Refrigerant lines (copper)

Refrigerant lines are the lifeblood of your wall-mounted heat pump. They ensure the circulation of refrigerant between the indoor unit and the outdoor compressor.

They are composed of:

  • Two copper tubes : a liquid line (thin) and a suction line (wider and insulated);
  • Waterproof and nitrogen-tested solders , guaranteeing zero leaks;
  • A modern refrigerant , often R-32 or R-454b , which is more efficient and environmentally friendly;
  • An aesthetic protective chute , inside and out, for a clean and durable finish.

At AirGreen , each installation is calibrated to the nearest millimeter: thermal insulation of the lines, controlled curvatures, and perfect sealing to ensure silence, efficiency and longevity of the system — even at -30 °C.

Condensate drainage

Condensate drainage

When the heat pump cools the air, it also removes ambient humidity: this water, called condensate , must be evacuated properly.

Our team installs a drainage system designed to prevent any leaks, odors or freezing :

  • Continuous outward slope for natural gravity flow;
  • Condensate pump installed discreetly if the difference in level does not allow it;
  • Insulated piping , resistant to cold and pressure variations;
  • Protected external outlet , anti-freeze and anti-air return.

Proper drainage protects your walls, ceilings, and floors from moisture. Our systems are designed to be as functional as they are invisible , resulting in clean, reliable, and long-lasting results—summer and winter.

Daikin – Historical innovator, but limited to Quebec

Great technology, but a restrictive service

Daikin is the creator of the R-32 refrigerant, used today by the entire industry. However, the brand only introduced its R-32 machines in Quebec in 2025 , while others had already done so in 2023. Their new range is reliable and well-designed , but several obstacles hinder its attractiveness.

1. Installation exclusivity : only Daikin-certified companies can install the brand. This has two consequences:

  • Higher prices , since competition is limited.
  • Parts are available more quickly only from Daikin installers . For us, who can repair but do not distribute Daikin, parts lead times are longer. As a result, in the middle of a heatwave, while Daikin installers are busy installing new machines, we are receiving more and more calls from customers with an old Daikin that cannot be repaired quickly due to a lack of after-sales service.

2. Disappointing subsidies : Their best 18,000 BTU wall-mounted machine, the Daikin Atmosphera R-32 , only heats to -25°C and receives a LogisVert subsidy of only $770 . This is far behind the Fujitsu Orion XLTH R-32 18,000 BTU ( $1,632 ) and especially the Sharp ZHU1 18,000 BTU ( $2,640 , the highest in Quebec).

In summary, Daikin offers interesting technology, but its closed model (exclusive installers + limited parts) and low subsidies make it a less competitive choice in 2026 , especially for customers who want a reliable and easy-to-maintain long-term investment.

Elios – A sub-brand of Midea

New R-454B machines, but not the top of the range

In 2026, Elios also adopted new refrigerants, including R-454B , which comply with environmental standards. But you should know that Elios is actually a sub-brand of Midea .

Since Midea has been marketing machines under its own name , innovation has been focused on the main range. Sub-brands such as Elios, Moovair or Comfortmaker receive reliable and decent models, but not the best technologies , which remain reserved for the official Midea brand.

👉 In summary: Elios offers affordable and efficient machines for the mid-range, but to benefit from cutting-edge innovations , you must choose the Midea range.

Discover ELIOS

Canair – A Preferred Sub-Brand of Midea

When distribution makes all the difference

Like Elios, Canair is a sub-brand of Midea . Typically, sub-brands receive simpler models, while cutting-edge innovations are reserved for the official Midea range.

But in the case of Canair, the situation is a little different: the brand is distributed by Descair (Deschênes) , which is also the official distributor of Midea in Quebec. This proximity gives Canair privileged access to some of Midea's best models , which is not the case for other sub-brands.

👉 In summary: Canair benefits from a direct and advantageous relationship with Midea , which makes it a particularly interesting sub-brand for those who want to enjoy Midea quality… at a more affordable price.

Moovair – A sub-brand of Midea

A popular brand, but increasingly different from Midea

In 2025, Moovair achieved excellent visibility in Quebec, notably thanks to the Protégez-Vous survey, where the brand was cited among the most reliable according to consumers. However, it should be remembered that Moovair is not an independent manufacturer: it is a sub-brand of Midea , one of the world's largest producers of heat pumps.

Moovair offers affordable and efficient machines, which explains its popularity. However, some recent innovations remain exclusive to Midea . For example, the all-new Midea EVOX G3 – one of the most advanced technologies currently available – is available only under the Midea banner.

At AirGreen , we respect Moovair and recognize its success, but we have chosen to work directly with Midea . This allows us to offer our customers:

  • The latest innovations available immediately .
  • Direct access to the best machines and their parts.
  • A long-term vision , since Midea increasingly reserves its most efficient models for its main brand.

👉 Moovair remains a valid option on the market, but at AirGreen we believe that to obtain the best ratio between innovation, performance and sustainability , it is more advantageous to choose Midea .

Comfortmaker – A sub-brand of Midea

A brand losing ground in Quebec

Comfortmaker is a sub- brand of Midea, meaning its models share some of the technology developed by the world's largest heat pump manufacturer. Historically, Comfortmaker has held a strong market share, but we are now seeing declining demand for the brand.

One reason is related to its Quebec distributor, TTI Climatisation , which now seems to be focusing more of its efforts on its other brands, notably Gree and Zephyr . These two brands are rapidly gaining popularity in Quebec, offering value for money and subsidies that attract more and more customers each year.

👉 Comfortmaker remains a decent option in Midea's sub-brand lineup, but current Quebec market dynamics show a shift in demand towards Gree and Zephyr , which benefit from better distributor support and growing recognition.

Trane – An American giant, but another reality in Quebec

Rebranded machines that struggle to convince

In the United States , Trane enjoys a solid reputation thanks to its partnership with Mitsubishi , which has resulted in mini-split heat pumps of exceptional quality . Unfortunately, the situation is different in Quebec.

Here, Trane doesn't manufacture its own mini-splits; the brand buys machines produced by Gree and resells them under its own name. The problem is that these models often come without certain modern technologies (such as integrated Wi-Fi), while being offered at high prices due to the reputation of the Trane brand.

👉 Result: While Trane remains prestigious in the United States, in Quebec its mini-splits do not reach the same level and do not offer the expected quality/price ratio. This is why, in our 2026 table, they do not rank as high as we would have liked.

A Trane alternative, but without the latest technology

Ameristar is a sub-brand created by Trane to offer a more affordable version of its mini-splits. As with Trane in Quebec, Ameristar machines are not manufactured by Trane itself: they come from Gree , the world's largest producer, and are then rebranded under the Ameristar name.

In practice, this means that Ameristar models are identical to Trane or Gree , but often come without the latest technology (like built-in WiFi or cutting-edge innovations that Gree reserves for its own brand).

👉 Ameristar may be suitable as an entry-level option, but to take advantage of the full technology and added value, it is often more advantageous to choose a Gree machine directly .

Haier heat pumps are good machines, known for their good quality and affordable price . At AirGreen, we installed many of them before the subsidy programs came along, as they offered excellent value for money .

Since LogisVert and provincial subsidies became a central criterion in the choice of an appliance, Haier has lost popularity. The problem isn't the machine itself, but the fact that it receives much lower subsidy amounts than other brands.

👉 For our customers, this means that a Haier model, despite its competitive initial price, often costs more than a high-end Japanese heat pump (Sharp, Fujitsu, Mitsubishi), which benefits from a significantly higher subsidy.

Napoleon – A discreet brand in Quebec

Less popularity, fewer benefits

Napoleon heat pumps perform well, but their low popularity in the Quebec market works against them. In practical terms, this means that after-sales service is slower than for well-established and widely distributed brands like Fujitsu, Gree, Sharp, or Midea.

Added to this is another disadvantage: the subsidy amounts available for Napoleon are relatively low. For consumers, this often translates into a higher final cost than with a competing brand that benefits from a larger subsidy.

👉 Bottom line: Napoleon isn't a bad choice per se, but it's less competitive than other options that offer more support and better subsidies, for a lower price .
